Problem with growisofs 5.21 and Plextor PX-712A DVD writer

[Pierre-Marie Signe <pierre-marie.signe@tiscali.fr>]

Hello,

I read several things on the net about DVD burning not working with k3b/growisofs
and Plextor drives, and I am facing the same issue :

OPC failed. Please try writing speed 1x.
Fatal error at startup: Input/output error

I am using growisofs 5.21, k3b version 0.11.14 and a DVD-R medium.
It does not seem to be a firmware problem since burning works fine on the same
drive and media with Nero6.

Does anybody have a solution ?
